Title: Photoelectric type potentiometer
Inventor: SATO MASUJI
IPC: H01L31/0232
Filed: 1988-11-07
Abstract: PURPOSE:To provide the potentiometer which is stable in output characteristics as against a temp. change by executing the transmission of light between a light source part and a light spot forming part as well as a light spot forming part and a photodetecting part via an optical fiber bundle. CONSTITUTION:The photoelectric type potentiometer is constituted of the light source part 1, the light spot forming part 2, and the photodetecting part 3. The forming part 2 is constituted apart from the light source part 1 and the photodetecting part 3. The transmission of the irradiating light A from the light source part 1 to the forming part 2 and the transmission of the light spot B from the forming part 2 to the photodetecting part 3 are executed via the optical fiber bundles 4, 5. Only the spot forming part 2 is mounted to a rotating system with which the temp. rise is high. The light source part 1 and the photodetecting part 3 are mounted to the position where the temp. change is small. the rotating angle is detected by the voltage corresponding to the light spot generated by the displacement of the measuring body. The influence of the temp. change is, therefore, decreased and the accuracy of the detection is improved.

Title: Heat sink device
Inventor: KAGA KUNIHIKO
IPC: H01L23/467
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a heat sink device, where the flow speed distribution of coolant is almost constant in the direction vertical to a heat sink base surface. SOLUTION: This device relates to improvement in the cooling performance of a heat sink device, and as a means of expanding the width of an air path formed between adjacent fins of the heat sink as the distance from a heat sink base in vertical direction increases, the thickness of a heat sink fin decreases as the distance from the heat sink base in vertical direction increases. Thus, the air current deviated to the fin base plane vicinity moves to above the fin for even wind speed distribution between fins. So the heat-transfer area is effectively assured over the entire height direction of the fin, resulting in a substantial improvement in cooling performance, while the cooling performance for the same volume is improved significantly. A detour air path in assured with respect to closure of air path due to deposition of dust, etc., for less performance degradation.

Title: Robot control system
Inventor: SHIRAISHI MITSURU
IPC: B25J9/16
Filed: 1985-12-14
Abstract: PURPOSE:To prevent the generation of excessive power and to ensure the smooth control operation of a robot by obtaining the controlled variable from the deviation between the present position and a designated position and comparing the controlled variable with the set maximum controlled variable so that the controlled variable is kept under the maximum controlled variable. CONSTITUTION:If the controlled variable ua of a controlled variable generating part 4 is positive and exceeds the maximum controlled variable umax, the output u1 of a multiplexer 72 reaches the variable umax. While the output u2 of a multiplexer 75 also reaches the variable umax. When the controlled variable ua is positive and less than the variable umax, the output u1 of the multiplexer 72 is equal to the variable ua. Then the output u2 of the multiplexer 75 is also equal to the variable ua since the variable ua is positive and larger than the minimum controlled variable umin. Both max. and min. controlled variables umax and umin can be set optionally by a CPU 6 according to the working contents and the type of an object. This prevents an excessive torque produced by a motor 1 even though the steady deviation is produced and the controlled variable ua is increased.

Abstract: PROBLEM TO BE SOLVED: To provide an accurate and efficient milling machining for a fan integrally combined with a rotor disc as a single body or an integrated assembled product with no individual dovetail joint, or for a blisk of a compressor. SOLUTION: A semi-operated product is formed up by means of milling cutting using a rotary mill.

Abstract: PURPOSE:To provide an operation stopping method with which the residual adsorbed oxygen at an oxidating agent electrode can be perfectly consumed substantially, by offsetting the reaction gas purging timing with an inert gas between two compartments for a certain while. CONSTITUTION:To stop or take pause of operation of a fuel cell, a breaker 32 is opened to shut the load current, and a three-way valve 11 is changed over to feed nitrogen 40 as inert gas to an oxidating agent compartment 5, and the oxidating agent 10 in this compartment 5 is purged through an outlet valve 10. This process elevates the potential of an oxidating agent electrode 3. A switch 3 is closed in the condition the fuel gas 20 is supplied to a fuel gas compartment 6, and a discharge resistance 33 is turned on to flow a small discharge current (i). Thereby the potential of the electrode 3 sinks greatly. Sink of the electrode potential can be sensed by monitoring drop of the current (i) with a current sensor 35. When the current (i) approaches zero, another three-way valve 21 is changed over to the supply system side for nitrogen 40, and the fuel gas 20 in the compartment 6 is purged, and the switch 34 is opened to shut the discharge current (i).
